defeat of Satan by the Archangel Michael. The process of exorcism is used within the Catholic Church against the Devil and demonic possession. According to The Catechism of the Catholic Church, "Jesus performed exorcisms and from him the Church has received the power and office of exorcising". Gabriele Amorth, the chief exorcist of the Diocese of Rome, warned against ignoring Satan, saying, "Whoever denies Satan also denies sin and no longer understands the actions of Christ". The Catholic Church views the battle against the Devil as ongoing. During a 24 May 1987 visit to the Sanctuary of Saint Michael the Archangel, Pope John Paul II said: Eastern Orthodox views In Eastern Orthodoxy, the devil is an integral part of Christian cosmology. The existence of the devil is taken seriously and is not subject to question. According to Eastern Orthodox Christian tradition, there are three enemies of humanity: Death, sin and Satan. In contrast to Western Christianity, sin is not viewed as a deliberate choice but as a universal and inescapable weakness. Sin is turning from God towards oneself, a form of egoism and ungratefulness, leading away from God towards death and nothingness. Lucifer invented sin, resulting in death, and introduced it first to the angels, who have been created before the material world, and then to humanity. Lucifer, considered a former radiant archangel, lost his light after his fall and became the dark Satan (the enemy). Eastern Orthodoxy maintains that God did not create death, but that it was forged by the devil through deviance from the righteous way (a love of God and gratitude). In a sense, it was a place where God was not, for he could not die, yet it was an inescapable prison for all humanity until the Christ. Before Christ's resurrection, it could be said that humanity had a reason to fear the devil, as he was a creature that could separate mankind from God and source of life — for God could not enter hell, and humanity could not escape it. Once in Hades, the Orthodox hold that Christ — being good and just — granted life and resurrection to all who wanted to follow him. As a result, the devil has been overthrown and is no longer able to hold humanity. With the prison despoiled, the devil only has power over whose who freely choose him and sin.
